An amazingly succinct and accessible answer to the question ''What is enlightenment?''--from one of America's most prominent teachers of Insight Meditation. One of today's most highly regarded Insight Meditation teachers describes the process of enlightenment in a way anyone can understand--demonstrating in clear language why we operate with the illusion of separation, how we can move out of it to the realization of emptiness and no-self, and how we can live from that state of awakening. He provides brief, powerful exercises that enable us to challenge the reality of our thoughts in order free ourselves from the illusion they keep us bound to, all the while steering us away from the temptation to regard spiritual practice as a process of self-improvement or a goal to be obtained.
